System for fishing

ABSTRACT

A data acquisition and retrieval system ( 11 ) for fishing. Input means ( 37 ) are provided for inputting: (i) geographical positioning data indicating the geographical position of a point for fishing in substantially real-time relative to a region: (ii) weather data indicating the prevailing weather conditions applying to the geographical position of the point in the region; (iii) fish data characterising the fish located at or obtained at the point; (iv) time data specifying the date, time or season corresponding to the real-time at the point; and (v) water condition data of the prevailing environment at the point. A database ( 60 ) is provided for storing the data input by the input means ( 35 ) relative to the geographical position of the point and linking the data to any previous data stored for the particular geographical position of the point. A graphical user interface accesses the linked data of the database and outputs it in an appropriate medium, usually a display that presents an image pane ( 141 ), for interpreting by a user of the system. The system is particularly suited to lobster or prawn fishing in the ocean and can be used to predict where to fish. A method for fishing based on the system is also described.

FIELD OF THE INVENTION

[0001] The present invention relates to a system for fishing and more particularly to a data acquisition and retrieval system for fishing, and a graphical user interface for use with such system.

[0002] Throughout the specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.

[0003] Furthermore, the term “habitat” throughout the specification will be understood to mean the physical geography of a region that may be inhabited by fish, such as the rocks, sand, seabed etc.

[0004] In addition the term “environment” throughout the specification will be understood to mean the actual water conditions of a region that may be inhabited by fish.

BACKGROUND ART

[0005] Commercial fishing is an activity that is still dependent to a very large extent on the skill and intuition of the individual fisherman.

[0006] Very successful fishermen will always try to ‘think’ like a fish and try to imagine where the fish would prefer to be. It is generally acknowledged that good predictions can often be made as to where to commence fishing from observing the habitats of the different species of fish, and noting historically where fish have been caught in the past and in what numbers.

[0007] In practice, however, there is also much “throwing and hoping”, as well as a lot of fisherman's intuition.

[0008] Consequently, many methods have been developed to bring a more scientific approach to fishing, but these have principally been related to methods of detecting the presence of fish in a given location or the preferred habitat for the particular fish being sought. These methods have predominantly used acoustic echo sounders and other reflective “wave” techniques as the means for detecting fish and/or their habitat.

[0009] Whilst these acoustic sounders, or echo sounders as they are more commonly referred to, can detect the preferred habitat for bottom-dwelling fish life, such as Western Australian rock lobster, they are unable to actually detect such fish life on the sea or lake bottom. The reason for this is that these fish appear to be part of the sea or lake bed itself, at least in so far as the acoustic sounder is concerned.

[0010] Acoustic sounders, however, are able to detect the physical presence of middle and top-dwelling fish life. However this only occurs when the vessel containing the acoustic sounder is virtually right on top of the fish.

[0011] Thus, in general terms, acoustic sounders may at best be described as fish detectors, but certainly not fish predictors.

[0012] Sometimes top-dwelling fish can often be detected by other natural means, such as bird activity, or alternatively, visual observation of surface water activity. Mostly, however, for these types of fish, surface fishing gear has to be set up on an ad hoc basis to see if fish are present in that area.

[0013] Whilst these techniques are effective in showing the quantity in species of mid-dwelling fish in a particular area and the likely habitat for bottom-dwelling fish, they do not detect the water conditions or the environment in that area. In this respect, it is believed that water conditions are more important than habitat to a fish, and in fact fish will follow water conditions that are favourable to them. Further, it is believed that certain types or species of fish do not like sudden changes in depth, water temperature, salinity and certain other environmental aspects, but they prefer to acclimatise slowly.

[0014] Contrary to popular belief, it has been established that the water in the seas, oceans, rivers and lakes of the world are not one homogenous mixture, but rather are a collection of very different patches of water. Whilst the temperature obviously varies according to the whereabouts in the world that the body of water in question is located, it has also been discovered that the acidity, dissolved oxygen, salinity, turbidity and ORP (oxygen reduction potential) also varies significantly.

[0015] Significant variations can occur within quite close distances to one another. For example, there are known places in oceans and seas where there are fresh water springs where there is obviously low salinity proximate to and downstream or down-current of the spring and high levels of salinity at places similarly proximate to but upstream or up-current of the spring. Indeed, the change in salinity is a factor experienced proximate to a river mouth, where differences in salinity can vary considerably dependent upon the season and rainfall.

[0016] It is believed that fish, like most other living species prefer to live in the most comfortable habitat and environment that they can find. However, if that habitat and/or environment should commence to degrade, the fish will move, if possible, to a better one.

[0017] Whilst habitat can change, generally it does so over long time periods. On the other hand, environmental changes may occur very quickly. An example of this is in the ocean where certain types of seaweeds can break free and then quickly decompose. The products of decomposition can include ammonia, methane, iodine, protein and hydrogen sulphide. amongst others. These products can rapidly affect the immediate environment proximate to the decomposing seaweed.

[0018] Whereas some species of fish, such as Western Australian bream or snapper can be very tolerant of a wide range of ammonia, they find even minute levels of sulphuric acid (as produced by the hydrogen sulphide dissolving in water to form sulphurous acid, combining then with the dissolved oxygen to form sulphuric acid) to be very toxic.

[0019] On the other hand, crustaceans such as crabs and lobsters are very intolerant of small amounts of ammonia, but can live in a wide range of ORP.

[0020] Yet again, tuna is very sensitive to temperature and iodine, but is insensitive to ammonia.

[0021] When the fish find this change in the environment uncomfortable, they generally commence to move to a better one.

[0022] Similarly, a temperature of a sector of ocean can not only change significantly from one locality to another, but also from one depth to another. For instance, under certain specific conditions, it is possible to have warmer water underneath colder water.

[0023] The temperature of the water in which the fish are living is therefore an important parameter, so that in the case of fish living at, or near, the seabed, the temperature of the water at that depth is much more important than the surface water temperature. Conversely, for top-dwelling fish, the water surface temperature or the thermocline up to 6 metres deep is believed to be the more important parameter.

BEST MODE(S) FOR CARRYING OUT THE INVENTION

[0106] As shown in FIGS. 1 and 2 of the drawings, the embodiment is directed towards a data acquisition and retrieval system 11 embodied in a personal computer (PC) system 13 and a controller interface system 15 which is installed on a lobster fishing vessel 16.

[0107] The functional layout of the data acquisition and retrieval system is shown in FIG. 2 of the drawings, whereby some of the functional components of the system are embodied in the PC system 13, and some in the controller interface system 15.

[0108] Having regard to FIG. 2 of the drawings, the specific components of the PC system 13 comprise the following:

[0109] PC computer 17 including a real-time clock (RTC) and conventional keypad;

[0110] wheelhouse hot panel 19;

[0111] deck counter panel 21;

[0112] deck number panel 23;

[0113] video display unit 25;

[0114] modem 27;

[0115] static input means 29 including a CD ROM and reader.

[0116] The various components of the interface system 15 comprise the following:

[0117] interface box 31 including interface processing means;

[0118] data input means 33 for inputting various dynamic and static data;

[0119] deck display 35.

[0120] The input means basically comprises suitable interfaces for accepting data input from various dynamic sensory sources and static sources on both the PC computer system 13 and the interface system 15. This data includes: geographical positioning data from a geographical positioning system (GPS) 37 indicating the geographical position of a point, being the fishing vessel 16 itself, in real-time relative to a geographical region; weather data indicating the prevailing weather conditions applying to the geographical position of the point in the region; and water condition data in respect of the prevailing water body environment at the point.

[0121] The geographical positioning data essentially comprises two components, the first being topological data indicating the topological features of a predetermined region for fishing and the second component being data indicating the position of the point with respect to this region.

[0122] The first component is essentially static reference data and can be obtained from digital maps showing the main topological detail of predetermined regions where fishing is to be undertaken. This data can be obtained from a separate device and input into the interface box 31 via one of the data input means 33, or alternatively may be provided in a software media form such as a CD ROM and loaded into the PC system 17 via the CD ROM reader 29.

[0123] The second component is generally dynamic data and can be derived from the GPS 37. The GPS 37 is generally a self contained and separate device that inputs data to the interface box 31 and across to the PC system 13 via the interface line 47.

[0124] The weather data comprises two components, one component being static data which may be directly input into the system via the modem 27, or alternatively input into the system via software media such as digital data stored on a CD ROM or floppy disc, in which case the data is loaded via the PC. The static data may comprise moon-phase detail and tidal information.

[0125] The second component is dynamic weather data which is obtained from discrete instrumentation located on the vessel and is fed in as digital data from a sensor or sensors 39 directly to the interface box 31. This dynamic weather data includes external weather conditions such as air temperature, barometric pressure, etc . . .

[0126] The water condition data essentially comprises all dynamic data pertaining to the particular locality of the fishing vessel or the point. The water condition data includes depth from a depth sensor 41, surface or depth water temperature from a temperature sensor 43, and other data generally represented at 45 such alkalinity or pH, dissolved oxygen content of the water, turbidity, swell and ORP.

[0127] The deck panel 21 is used for inputting additional dynamic data into the system including fish data characterising particular fish located at, or obtained at, the location of the vessel or point.

[0128] The wheelhouse hot panel 19 is used to simplify control and operation of the PC computer system 13 by the skipper of the vessel, which can alternatively be done via the main keypad of the PC computer 17. The hot panel, however, is more robust and simpler to operate than the main keypad, being more suited to the vigorous environment on a lobster fishing vessel.

[0129] Finally, the RTC is provided for inputting the real-time into the system so that any data captured or entered into the system at a particular point in time, is correlated to the real-time that this data capturing or inputting is undertaken.

[0130] The arrangement of the various components on the lobster fishing vessel is shown in FIG. 1. The PC computer 17, interface box 31, wheelhouse hot panel 19 and visual display unit 25 are all located in the wheelhouse 49.

[0131] The deck number panel 23 is located just behind the wheelhouse 49 at the pot pulling area 51 in front of the winch 53, the deck counter panel 21 is located at the pot counting area 55 just behind the winch 53 and the deck display 35 is also located just behind the wheelhouse 49, but on the opposite side to the pot pulling area 51 to enable it to be seen all deckhands.

[0132] The PC computer system 13 and the interface box 15 are operated by an operating system and application software the processes of which are shown in FIG. 4. These software processes not only manage the operation of the PC computer system 17 and controller interface system 31 with respect to the inputting of various data, but also operate a database management system (DBMS) 57 to store and process data in a database 59 and output relevant processed data from the database to enable monitoring and controlling of the fishing operation. This data can be retained for further analysis and the generation of a fishing history in the area.

[0133] As shown in FIG. 4, the processes include different modes such as navigation and way point interpretation 61 for the vessel 16, a drop pots mode 63 for storing pot location data, and a pull pots mode 65 for recording the catch data, all of which feed into the database 59.

[0134] The button 66 on the hot panel 19 selects between these different modes of operation.

[0135] The navigation and way point interpretation 61 is standard working off the GPS 37 and involving processes for determining latitude 67, longitude 69, boat speed 71 and bearing 73.

[0136] The depth is also input to the DBMS under this mode using the depth sounder sensor 41.

[0137] The drop pot mode 63 and the pull pot modes work off a deck panel process 75 and a wheelhouse keyboard/panel input process 77. The former controls the deck counter panel 21 and the deck number panel 23, and the latter controls the hot panel 19 and the main keypad for the PC computer 17.

[0138] A probe data process 79 for handling dynamic data concerning water and weather conditions 81 and 83 respectively, also inputs data into the database 59. Static data such as moon phase 85 and swell 87 is input directly into the database 59, with the aid of the wheelhouse keyboard/panel input process 77.

[0139] The software processes also control the output of the database 59, in particular the main display provided via a graphical user interface (GUI) on the visual display unit 25. These processes include an edit data process 89 and the GUI 91 itself, which also displays a depth chart 93. The GUI 91 displays a map or image panel of the topological features of the area, an example of which is shown in

[0140]FIG. 3 of the drawings. The GUI 91 is controlled by program options 95 and includes bit map overlay files 97 to help create a layered image.

[0141] The deck display 35 is also controlled from the DBMS 57.

[0142] For subsequent analysis and further processing of data, a data exchange process 99 and file output process 101 extract data from the database 59 and feed it into a data interrogation and prediction module 103.

[0143] The database 59 is arranged to store the aforementioned data input into the system in discrete records of a particular entity corresponding to the fish type or species, and where each of the records include fields corresponding to the aforementioned data which is input into the system. Each record of an entity would be referenced according to time and locality and the remaining data entered in the relevant fields manually and automatically, as appropriate.

[0144] In general, the system stores individual records of the following information:

[0145] What was caught (fish type, quantity);

[0146] Where it was caught (grid location provided by GPS);

[0147] When it was caught (date, time, season);

[0148] External conditions on which it was caught (moon phase, air temperature, barometric pressure, etc . . . ); and

[0149] Water conditions (depth, various temperatures at intermediate depths, dissolved oxygen, ORP, turbidity, pH, swell, etc . . . ).

[0150] The keyboard and panels are used to enter data and operate the PC as appropriate. The GUI in the present embodiment is Windows™ and provides for interactive operation by an operator of the system.

[0151] The counter panel 21 is used to count the fish and enter data relating thereto. In the case of lobster, record is taken of whether lobster pulled in a pot shown at 105 and counted at 107 in FIG. 1, are male or female by pressing buttons 109 and 111 respectively, and buttons for other relevant data. The number panel is used for entering the number caught and the pot numbers, if necessary.

[0152] In practice in the data acquisition mode, the system operates so that the various data is continuously being input to the system from its various sources. Whenever fish are caught, the volume and/or weight of those fish is either manually or automatically entered by the fisherman on the boat using the keypad 19 or keyboard 27 into the system and the actual real-time dynamic data input to the input means 17 at that instant is also recorded and stored in the database, in conjunction with the time data obtained from the RTC.

[0153] The graphical user interface can be used to display historical information stored within the database for different locations within a predetermined region. The specific arrangement of the graphical user interface for this purpose is best described by reference to the particular display that will be provided to a user of the system, as shown in FIG. 3 of the drawings.

[0154] Moreover, the computer program is designed to display an image pane 141 on the display 25 which includes the typical Windows™ menu, control, tool and task bars 143 at a peripheral part of the pane and a graphical representation 145 in the remainder of the pane.

[0155] The graphical representation 145 displays the topological features of a selected predetermined region in which fishing is desired to be undertaken.

[0156] The computer program includes layering means to extract data from the database pertaining to specific locations within the displayed region at which data was previously captured and stored within the database, by the vessel. The layering means causes indicia to be layered on the image pane 141 in a manner so as to graphically indicate the relative locations in the predetermined region where this data logging had been undertaken. In the present embodiment as shown in the drawings, this is indicated by a diamond shape 147 a, circle shape 147 b and square shape 147 c being superimposed on the topological features of the predetermined region.

[0157] These shapes represent different time related factors associated with pots that are set at any one time. The diamond shape represents a pot just released, a circle shape represents that the pot has been at that location for less than 36 hours, and the square shape represents that the pot has been at that location for more than 36 hours.

[0158] The computer program also includes linking means which is associated with each indicium or box 147 to generate and display a table of data logged by the fishing system at the location indicated by the indicium. This data is extracted from the database using a predetermined selection criteria which may be designed and modified via the menu and toolbar of the graphical user interface.

[0159] The computer program also includes selecting means in the form of a mouse pointer 149 to select an indicium 147 and activate the linking means for the selected indicium 147. On activation, the linking means generates and displays the logged data in accordance with the definition of the selection criteria from the database for the location represented by the selected indicium 147 and displays this data in a table 151 superimposed on the image pane, adjacent the mouse pointer 149.

[0160] The table 151 can be opened and closed in a toggle manner using mouse clicks.

[0161] The application software which effectively operates the PC also includes a number of routines for performing different types of processing on the data stored within the database. In this respect, data which is linked to previous data stored for the particular geographical position of the point can be processed and related in accordance with predetermined parameters and/or formulae to generate information for subsequent storage in the database and outputting on the display means or a suitable printer connected to the PC 13.

[0162] In the present embodiment, one of the parameters is concerned with identifying the minimum value in the recorded water condition data or weather data at a particular location (or over a number of such locations) providing high fish data. Another parameter is concerned with identifying the maximum values, or optimum values. This can be done on a species by species basis to determine what the optimum or ideal fish conditions are for that particular species.

[0163]FIG. 8 shows the type of data that may be output after processing by the processing means and which may be printed out on the printer for different fish types or species.

[0164] In addition, the processing means includes a routine to be able to view all historical records stored in the database to determine past fishing performance at any location, or time, or weather conditions, or sea temperature or other field in the records, or any combination of such fields in the records, such as:

[0165] catch to date for season for

[0166] exact location;

[0167] general zones;

[0168] catch by month for:

[0169] exact locations;

[0170] general zones

[0171] catch by week for:

[0172] exact locations

[0173] catch by day for:

[0174] exact locations

[0175] general zones

[0176] catch by year for:

[0177] exact locations

[0178] general zones.

[0179] Routines are also provided to calculate various statistical averages such as:

[0180] average catches;

[0181] per day fish, per month, per week, per location, per general zone.

[0182] Further still, routines are provided to perform useful calculations, such as:

[0183] direction of change of swell (rising or falling);

[0184] rate of change of various temperature;

[0185] boat distance travelled;

[0186] fuel used;

[0187] shortest distance to travel to fish.

[0188] The application software also includes a routine which is run in real-time, concurrently with acquisition of data, whereby optimum fishing conditions for different species are loaded into a reference zone and instantaneous data acquired from the various sources, compared against this reference.

[0189] Accordingly, the vessel can acquire real time data in relation to the water conditions over a predetermined geographical region by operating in a trolling mode to determine the best locality for fishing for a particular type or species of fish, having regard to the acquired data.

[0190] After surveying the predetermined region, the system is then invoked to identify the best locality to fish and the vessel is then returned to that locality to fish it.

[0191] The particular application software that can achieve the aforementioned functionality can be written a number of different ways and would be within the common general knowledge of a software programmer skilled in database management systems, databases, and interfacing with instrumentation using microcontrollers. Accordingly, the specific layout of the computer program will not be described.

[0192] It should be appreciated the scope of the particular is not limited to the specific embodiment described herein. Accordingly, many variations to the application software and functionality can be made in order to utilise the data stored in the database using the data acquisition and retrieval system without departing from the spirit or scope of the present invention.
